Hey Up,
When you go to sign on at the paddock office you will be allocated a place to be,this will be with marshals who have done the TT before and at no time will you be left on your own.
I marshaled at the Manx a few years ago and since then have done Moto GP,Superkart GP,Motocross GP,car marshaling and club race marshaling all over the UK.
I would like to get over to the TT or Manx again,but it's so expensive to get over I might not make it again.
Marshaling over here you sometimes get a little travel money and some clubs give you a breakfast voucher + packed lunch,at EMRA meetings at Mallory you get a bag of treats = can of drink,crisps,sweets and a banana!
The best thing is you are with other people who are there for the same goal,which is to help the sport out and then have a good time in the evening.
